The PNGOC said in a statement that it was aware of a complaint made against the Commonwealth Games gold medallist and that it "looks forward to a speedy resolution of this matter", but reiterated that Toua is still a member of the nation's Olympic team.

Chef de Mission Tamzin Wardley also rubbished a claim that an arrest warrant had been issued for Toua, who is currently in quarantine in Australia ahead of resuming training there.

"The court was quite adamant they decided not to issue a warrant for her arrest and they certainly have not made any request to the Australian police to make an arrest or even contemplate extradition," Wardley told ABC Radio Australia.

"All these issues are affecting her, and we'll be in touch with her over the next couple of days to make sure she still feels capable of sorting out her training down there.

"Every effort is being made to make sure she's in the best possible fitness for the Tokyo Olympics."

The National had reported that the complaint related to an alleged assault, and that accusation had been denied.

Toua won the women's 53-kilogram title at the Glasgow 2014 Commonwealth Games.

A three-time Commonwealth Games medallist and three-time Pacific Games champion, Toua is perhaps best known for being the first woman to compete in weightlifting at the Olympic Games, when it was added to the programme for Sydney 2000.

Toua was PNG's flagbearer at the Athens 2004 Opening Ceremony and also competed at Beijing 2008 and London 2012.

Toua will be the first female weightlifter to compete at five Olympics should she make it to Tokyo 2020.

The PNGOC's statement, which highlighted many of these achievements, finished by saying that Toua "has always represented Team PNG and Papua New Guinea with distinction."
